Specification of Letters Patent.

Patented Aug. 14., 1917.

Application filed November 22, 1916. Serial No. 132,850.

To all whom it may concern:

Be it known that I, CARL A. WAGNER, a citizen of the United States,residing at Danville, in the county of Boyle and State of Kentucky, haveinvented certain new and useful Improvements in Turning, of which thefollowing is a specification.

The object of this invention is to provide improvements in the art ofturning wood or other material.

This and other objects of the invention will be illustrated in thedrawings, described in the specification and pointed out in the claimsat the end thereof.

In the drawings,

Figure 1 is a side elevation of a lathe equipped for carrying out myinvention.

Fig. 2 is a vertical section on the line 2 2 of Fig. 1.

Fig. 3 is a horizontal section on the line 3 --3 of Fig. 2. I

Fig. 4 is a sectional elevation showing a modified form of the rest forsupporting the guide.

Fig. 5 Fig. 1.

Figs. 6, 7 and 8 are end and side elevations of special cutting tools tobe used in connection with my invention.

In the drawings like reference numerals indicate like parts.

In the drawings reference numeral 1 indicates the bed of a lathe havingthe head stock 2 and the tail stock 3. In the head stock is mounted torotate the cone pulley 4 which drives a shaft 5 having a live center onthe end thereof and a face plate 6.

On the tail stock is mounted the dead center 7 between which and thelive center 5 the blank 8 is adapted to rotate. In front of the blank 8is carried a pattern 9 supported on a rest 10 which in turn is supportedfrom the shoe 11. The rest is supported on an upright 22 in which is aslot 12 through which passes a bolt 13 havlng a head 14 on the outer endthereof. This bolt passes through the upright 15 of the shoe. The outerend of it is threaded and is engaged by the hand wheel 16 by which it isclamped in place holding the upright of the rest between the head 14 andupright 15, and thus holding the rest in any desired position on theshoe. The uprights 15 and is a section on the line 5"5 of 22 arechanneled so that the one nests into the other as is shown in section inFig. 3. The base of the shoe has a slot 17 therein and the bed of thelathe has a slot 18 therein, extending transversely to the slot 17.Through these slots passes the bolt 19 by which the shoe may be clampedin any desired position, that is, it may be moved in or out or movedalong the bed of the lathe and clamped as may be desired.

The rest 10 has an inclined bed 20 thereon on which the pattern 9 may befastened by one or more screws 21. The top of the pattern is ordinarilyplaced below the top of the blank 8. This pattern is inclined upwardlytoward the stock.

The working surface of the pattern is sawed out to the desired shapewith a band saw and is then fastened on the rest. Tools such as areshown in Figs. 6, 7 and 8 are used. These tools have a cutting edgewhich corresponds to the outline of a short section of the pattern. Thetool is laid snugly on the particular part of the pattern that it isintended to fit and the tool is then moved forward so that the cuttingedge of it engages withand cuts the blank. The tool is advancedtangentially to the blank cutting its way through it and being held tothe in clined position fixed by the pattern. When the tool has cut itsway clear through the stock it will leave the blank cut to correspondwith the shape of the pattern in that particular section.

Another tool is then used in connection with another section of thepattern and the blank is cut away by it in like manner. The depth towhich the various tools cut the stock is indicated by the dotted circlesand the lines tangential thereto, shown in connection with the blank 8in Fig. 2. In addition to the special tools which are shown in outlinein Figs. 6, 7 and 8 the ordinary cutting tools, such as are used in woodturning, may be used as well.

In Fig. 4 I have shown a modified form of a rest in which the shoe isindicated at 25 and is provided with a socket 26 in which is mounted astem 27 of the rest 28, on which the pattern 29 is carried. Mounted inthe shoe 25 is the threaded stud 30 on which is engaged the adjustmentsleeve 31 which may be turned up and down thereon. This sleeve is shapedas shown in section in Fig. 5. On the top of the sleeve is a pin 32which engages with the socket on the under side of the rest 28. Byturning the sleeve 31 up so that the pin 32 engages the socket, the rearedge of the rest will be firmly supported. The stem 27 is clamped inplace by the hand wheel 33 which has a threaded stem 34 thereon whichengages with the threaded opening in the socket 26 which is used toclamp the stem 2-7 in any desired position. The stem 27 is released byturning the hand wheel 33 which then permits the raising or lowering ofthe rest. lhe adjusting sleeve 31 can be turned up or down to correspondwith the position of the rest desired, after which the rest may beclamped in positionby the hand wheel 33. In this way the rest may beadjusted up or down to secure the proper elevation with relation to theblank 8, after which the blank 8 may be turned down by the use of thetools, as above described.

It will thus be seen, that when any desired round shapes are wanted apattern can first be sawed in a block with a bandsaw after which thepattern may be fastened in the rest and the rest may be properlypositioned with regard to the blank that is to be turned. in the lathe.The proper tools may then be laid upon the particular sections of thepattern as needed and moved straightforward and the tools being guidedby the Copies of this patent may be obtained for five cents each, byaddressing the Commissioner of Patents,

pattern to make the proper cutting eflect both as to width and depth.After the various tools have been used in this manner the blank will befound to be cut or turned to conform to the pattern and a series ofblanks may in like manner be turned from the same pattern, each of saidblanks having the same side elevation as the pattern.

I claim.

1. The method of turning which consists in fashioning a pattern with avarying contour and with a transversely flattened surface of sufficientwidth to permit a tool to be steadily held and guided thereon withoutrocking motion; and supporting said pattern rigidly so that itsflattened transverse surface is tangential to the finished work.

2. A pattern guide for controllinga hand operated wood turning toolcomprising a transversely fiat surface of suificient width to enable thetool to be held steadily thereon without rocking and havinglongitudinally a varying contour and means for mounting and holding saidpattern rigidly so that its fiat transverse surface shall lie in theplane of a secant to the blank or tangent to the finished work.

In testimony whereof I afiiX my signature in presence of two Witnesses.
